History and construction

Canadair began work on the CL-28 in April 1954. At the time, it was the largest aircraft ever built in Canada. The CL-28 was derived from the Bristol Britannia , with the same wings, tail unit and landing gear, but "Americanized" - which means that the same basic design was used, but the British materials and standard parts were converted to North American dimensions. The fuselage was completely redesigned by Canadair, from the pressurized cabin of the Britannia to a non-pressurized, new fuselage with a reinforced structure with bomb bays in front and behind the wings. Instead of the Bristol Proteus turboprop engines, Wright R-3350 turbo-compound engines were chosen as engines , as these had lower fuel consumption, which made longer patrol missions possible. The Argus Mk. I first flew from the Canadair factory in Montreal on March 28, 1957. 12 more machines with Mk. I standard followed. This was followed by 20 examples of the Argus Mk. II. Production ended in July 1960. At the beginning of its career, the CP-107 Argus , as it was called by the Canadian Air Force, was considered the best aircraft of its type.

The Argus replaced the Lancaster and Neptune previously used in maritime reconnaissance and anti-submarine combat with the Royal Canadian Air Force .
